Some men are destined for danger Texas Ranger Tom Bell is simply tracking a fugitive killer in 1931 when he rides into Kilgore, a hastily erected shanty town crawling with rough and desperate men—oil drillers who've come by the thousands in search of work. The sheriff of the boomtown is overwhelmed and offers no help, nor are any of the roughnecks inclined to assist the young Ranger in his search for the wanted man. In fact, it soon becomes apparent that the lawman's presence has irritated the wrong people, and when two failed attempts are made on his life, Bell knows he's getting closer to finding out who is responsible for cheating and murdering local landowners to access the rich oil fields flowing beneath their farms. When they ambush him for a third time, they make the fatal mistake of killing someone close to him and leaving the Ranger alive. Armed with his trademark 1911 Colt .45 and the Browning automatic he liberated from a gangster's corpse, Tom Bell cuts a swath of devastation through the heart of East Texas in search of the consortium behind the lethal land-grab scheme.

There is no peace in the hard country Tucker Snow is as tough as they come, hardened by decades working as an undercover narcotics agent for the Texas Department of Public Safety. Through special dispensation from the governor, he and his brother Harley cut a wide swath through the criminal element of Northeast Texas. But tragedy comes calling after taking a dream job as a special ranger with the Texas and Southwestern Cattle Raisers Association, when Tucker's wife and toddler are killed in a horrific traffic accident caused by a drug addled felon. Close to breaking, Tucker sets his badge aside to move his surviving teenage daughter outside of Ganther Bluff, a quiet town with enough room for them to mourn their unexpected loss. But peace doesn't last long for a man like Tucker Snow. Instead of settling into small-town life to heal from such an unimaginable loss, a fresh kind of hell hits them with full force. Crimes and secrets strangle this rural community, and when a new form of meth with the street name of gravel gets too close to home, it's enough for Tucker to put his badge back on and call Harley for help. The town will ultimately be better off with him as a resident lawman, but this unforgiving landscape will threaten everything Tucker holds dear.
